ELECTRICAL VAPOR-IZER Application filed June 2, 1928.

My invention relates to electrical vaporiz-' ers of the individual hand type for the treatment of head colds and other head afllictions by generating vapors of any desired medicament and applying them, by inhalation, while hot. My present invention is an improve ment on the construction shown in my 00- pending application, Serial No. 194,180, filed May 25, 1927 (Case 27 1). Among the ob jects are to simplify that construction, reduce its cost of manufacture, provide means for measuring or predetermining the amount of medicament to be conveyed to the heating element for vaporization, render the device easier to handle, and simplify keeping it in a sanitary condition.

In the drawings, Figure 1 is a side elevation of my improvement.

Figure 2 is a part sectional elevation there Figure 3 illustrates a container for holding liquids to be vaporized by my invention. In this view is also illustrated a sup port or holder for maintaining the container 5 in position, and

Figure 4 is a vertical sectional view through the cover or plate 7 of Figure 2.

Referring to the drawings:

My invention consists of a hollow handle or base 5 made of any suitable material which terminates at its upper end in the enlarged portion shown. lVithin the handle any suitable heating element and electric switch, preferably of the type illustrated in my copendmg application, Serial No. 212,111, filed August 10, 1927 (Case 279) is suitably mounted with the heating element in the enlarged upper end of the handle. The usual electric cord 6 extends upwardly through the lower end of the handle and is connected to the switch in any proper manner. As my present invention does not relate to the construction of these parts, they are not illustrated in the drawings, it being understood, as stated, that any suitable form of heating element and switch may be used.

Over the upper end of the handle 5 a cap or cover 7 is removably mounted. The cap is of any material suitable for the purpose preferably thin nickel-plated steel, or silver. The

Serial No. 282,359.

cap is so mounted on the upper end of the handle as to provide for ventilation for the heating element.

A hollow hood or nasal member 8, generally cone shape in outline, is removably pressed over the cap 7, as shown in Figures 1 and 2. At one side the hood contains a chamber 9 containing the medicament to be vaporized, a non-liquid compound. This chamber threadingly receives a plunger 10. The threads are of such pitch that by one-half turn of the plunger forces a sufficient amount of the medicament through the pin-hole 11, onto the concave upper face of the cover 7, for one average treatment from the vaporizer. The plunger is provided with an opening 12 to receive a hook or nail in hanging the vaporizer up. At opposite sides the hood 8 is provided with air vents 14:. The hood may of course be made of any desired material such as hard rubber, bakelite or glass.

In operation the plunger 10 is turned onehalf revolution which forces a small amount of medicament upon the concave face of the cover 7. When the switch 15 is pressed the cover is quickly heated by the heating element within the upper end of the handle 5, and the medicament is almost instantly vaporized. During this operation the nasal button or hood 8 has been placed in the nasal passage, whereupon the vapors generated are, by inhalation, lifted upward through the opening 16 in the hood 8 and are carried directly to the ailiictcd membranes while hot. Drafts of air, during this operation, are drawn into the hood through the openings or vents 14, and are heated prior to being lifted out of the hood with the vapors generated. The hollow body of the hood, and the heating element used, may be said to constitute a heating chamber.

When it is desired to clean the vaporizer it is only necessary to lift the nose piece 8 off the upper end of the handle 5, at which time it, and the cap or cover 7, may be thoroughly cleaned and sterilized.

In Figure 8 is illustrated an auxiliary part of my improvement for use particularly in vaporizing liquid medicaments. This consists of a bracket or holder 18 which sets over the cover 7 after the nose piece or hood 8 has been removed. The holder is preferably provided with spring fingers 19 which grip acontainer 20 of suitable material such as glass and hold it in contact with the cap 7. The liquid or other form of medicament to be vaporized is put into the container, and the nasal button 21 is then inserted as shown. Suitable elongated air vents are formed in the sides of the nasal button 21 so that on inhalation air rushes therethrough into the container and is lifted upwardly through the nasal button into the nasal passages. This construction is very similar to that shown in Figures 1 and 2 of my co-pending application Serial No. 19l,l37, filed May 26, 1927 (Case 275).

What I claim is:

In a device of the class described, a cylindrical hollow handle containing an enlarged upper end, a suitable electric heating element and switch mounted in said handle with the heating element adjacent said npepr end, a thin metallic cap slipped over said upper end, the upper face of the cap being concave, a hollow perforated hood slipped over said cap and removably mounted thereon and having vents formed in the sides thereof, a. chamber or magazine at one side of said hood, the chamber having a small outlet traveling in the direction of the concave upper face of said cap and positioned adjacent thereto, a nd a part in said chamber for forcing a predetermined amount of said medicament onto said cap for vaporization.

In testimony whereof I al'fix my signature.

JOSEPH ROBINSON.
